| Abstract: | A single step ultrasonic method (20kHz) is demonstrated for the formation of acetylsalicylic acid-Fe3O4-graphene oxide nanocomposites (~ 80 nm) in aqueous solution. The electronic molecular structure of these nanocomposites is stable in acidic or basic aqueous medium. Coating of these nanocomposites with polyvinyl alcohol (PVA) occurs through increased binding with drug, magnetite, Fe(II)-C-O and carbonaceous network of graphene oxide. PVA-coated-acetylsalicylic acid-Fe3O4-GO nanocomposites substantially improve acetylation of pristine ascorbic acid than free unmodified drug or uncoated acetylsalicylic acid-Fe3O4-GO nanoparticles due to enhanced electron density through the presence of magnetite and graphene oxide, and specific binding of PVA with drug and ascorbic acid. |
